Abstract: The invention comprises hexahydro-benz-[cd] indoles of the formula <FORM:0774986/IV(b)/1> where R1 is alkyl (C1-C8), and acid addition salts thereof.  These are made by reacting N-acyl-4-halo-5-oxo-hexahydro-benz[cd] indoles (see Specification 774,985) with alkylamino-acetone ketals and then hydrolysing the products with a strong non-oxidizing mineral acid.  An example is given of the condensation of N-benzoyl-4-bromo-5-oxo-hexahydrobenz[cd] indole with methylamino-acetone ethylene ketal and hydrolysis of the benzoyl and ketal groupings in the product.  Other starting materials are mentioned in which the N-acyl group is acetyl or benzoyl (or in general aliphatic, aromatic or araliphatic), R1 is methyl, ethyl, propyl, butyl or heptyl and the ketal group is ethylene, propylene or diethyl (C1-C8 alkyl in general).  The products are intermediates for the synthesis of lysergic acid and its homologues.  Alkylaminoacetone ketals of the formula <FORM:0774986/IV(b)/2> where R1 is C1-C8 alkyl and R2 and R3 are lower alkyl or together represent an alkylene chain of 2-3 carbon atoms, are made by condensing the corresponding chloroacetone ketal with the appropriate alkylamine.

Title: Manufacture of basic esters
Filed: 1939-07-12
Abstract: 531,208. Basic esters. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). July 12, 1939, No. 20307. [Class 2 (iii)] Basic esters of the general formula where R, and R 2  are aryl groups, R 3  is a basically substituted alkyl radical and R 4  is an alkyl or aralkyl radical, are prepared by reacting a nitrile of the general formula <SP>R</SP>1# CHÀCN  with an alkyl halide containing R 2 # a tertiary amino group as substituent in the presence of an agent for splitting off hydrogen halide, and transforming the tertiary nitrile thus obtained into the corresponding ester. The compounds are stated to be excellent spasmolylica. In examplas (1) Sodium amide is added to diphenylacetonitrile in benzene solution and then to the reaction product there is further added a benzene solution of piperidineethyl chloride. On the addition of acid there separates the hydrochloride of diphenylpiperidino-ethylacetic acid nitrile which is converted to the base by means of alkali. This compound is then heated with sulphuric acid in an oil bath to 145‹-150‹ O. to effect hydrolysis of the nitrile. Ethyl alcohol is then added and after the esterification there is obtained the ethyl ester of diphenylpiperidino-ethylacetic acid. Instead of piperidino-ethyl chloride there may be used diethylaminoethyl chloride to give dipbenylethylaminoethylacetic acid ethyl ester. (2) The saponification product of diphenylpiperidino-ethyl-acetonitrile prepared as in example (1) are esterified with isopropyl alcohol to give the corresponding isopropyl ester.

Title: Improvements in or relating to mechanical servo mechanism
IPC: B60T13/04
Filed: 1938-07-09
Abstract: 516,037. Spring-applied brakes. BENDIX, Ltd., and IRVING, J. S. July 9, 1938, No. 20344. [Class 103 (i)] In mechanism for providing spring assistance in the application of brakes &c., a pedal or hand-lever is connected to a plunger acted upon by a pre-loaded spring, which when its loading is exceeded by the brake resistance, permits relative movement between the plunger and its container to operate a clutch, whereby another movable member is actuated to cause spring-loaded servo means to apply a thrust through another clutch to the brake transmission. The pedal or lever is connected to an eye 11 on the end of a plunger 12 slidably mounted in a sleeve 14, with a pre-loaded compression spring 16 interposed between the end of the sleeve and a collar 17 on the plunger, the other end of the sleeve 14 being closed by a plug 18 having an eye 19 for the connection-of a rod or cable leading to the brakes. When the resistance offered by the brakes to the initial movement of the sleeve 14 exceeds the loading of the spring 16, the plunger 12 slides relatively to the sleeve 14, and a conical head 15 acts on balls or rollers 22 to clutch the sleeve 14 to an outer sleeve 21, which is thus moved to the left, thereby rocking over centre the inner ends of spring-loaded plungers 30 mounted in a housing 10, the plungers 30 then exerting an axial force on the sleeve 21. The sliding movement of the sleeve 21 causes a tapered bush 27 to force spring-controlled balls 25 into engagement with the inner sleeve 14, so that the force applied by the plungers 30 to the sleeve 21 is transmitted to the sleeve 14 and so to the brakes.

Title: Improvements in or relating to counting apparatus
IPC: H01J31/06
Filed: 1953-07-23
Abstract: 761,135. Electronic counting apparatus. BURROUGHS CORPORATION..July 23, 1953 [Oct. 15, 1952], No. 20503/53. Class 106 (1). A bidirectional counting appar. atus comprises a pair of separate counting means arranged to advance in opposite directions and each capable of being advanced through a succession of stable conditions upon receipt, from a common source, of signals representing units to be counted, and means for rendering only one of the counting means operative to count at any instant whereby applied signals may selectively be counted in one or the other direction. Two thermionic vacuum counting tubes A, B of the type employing a movable trochoidal beam, have their main anodes 107, 108 interconnected: also, corresponding " spade " anodes 82 ... 101 are coupled together and connected through RC circuits to a source of potential 104. Magnetic coils around each tube (not shown) are arranged to produce fields of opposite polarity so that the electron beams in the respective tubes will rotate in opposite directions in response to input pulses. The selection of the tube to be operated by the negative input signals from a terminal 130 is controlled by a two-state trigger circuit (not shown) which is connected between the grids 119, 120 of valves 115, 116, whereby only one of the cathodes 113, 114 of the tubes A and B is held at a potential sufficient to maintain a trochoidal beam across the tube. The electron flow of the beam in the operative tube causes the capacitance in the RC circuit of the " spade " anode upon which the beam impinges to become charged, so that when the trigger circuit is switched over and the operative conditions are transferred to the other counting tube, the charged capacitor establishes the beam to the corresponding " spade " electrode in the other tube. Since the tubes are arranged to be stepped round in opposite directions, the arrangement enables positive and negative items to be counted. Zeroizing is performed by transferring a switch arm 133. Tubes of the type described in Specification 759,153, details of which are also given in the present Specification, may be employed in the apparatus. These tubes employ apertured collector rings to give a binary indication of the number registered in a tube.

Title: Improvements in method and means for making wrought pipe fittings
IPC: B21C37/29
Filed: 1948-08-05
Abstract: 677,718. Making pipe fittings. WURZBURGER, P. D. Aug. 5, 1948 [Aug. 23, 1947 No. 20724/48. Classes 83 (ii) and 83 (iv). Stamping.-In a method of making tubular T and like fittings by confining a tubular blank in a die and then by endwise pressure both on the blank and on a body of filler material, confined and sealed therein, shortening the blank to form a head and causing it to flow laterally to form a leg or legs while the filler is maintained under a substantially uniform pressure during the operation and caused to flow into the leg or legs at a lesser rate than the rate at which the volume of the head portion of the blank is diminishing. A tubular blank 1 is enclosed in a die 2, Fig. 2, and is compressed by plungers 19, 20, while a filler 11 within the blank is compressed independently by plungers 13, 14 passing through the plungers 19, 20 and being operated preferably by hydraulic means so as to exert a substantially uniform pressure on the filler, which is preferably a polyethylene glycol of molecular weight between 1000 and 7000. By forming one of the inner plungers with a bore, a liquid filler could be introduced into the blank. In a modification, Fig. 4, the outer plungers 34, 35 are thicker and have reduced portions 40, 41 which act on a part of the filler and shoulders 37, 38 which compress the ends of the tube. In another form, both the tube and the filler are acted on at one end by a solid shouldered plunger, the uniform pressure on the filler being maintained by an inner independently operated plunger at the other end. In other modifications, solid plungers are used at each end of the die and the uniform pressure of the filler is obtained indirectly, in one form, Fig. 8, by using a block of filler 72 with a bore 73 containing a rod 74 over the ends of which the plungers 60, 61 advance and in another form, Fig. 11, by using a filler block with an axial bore 91, the rod 74 and the bore 91, respectively, being of such a size as to take up what is normally an excess of filler caused by the reduction in volume of the blank during the operation.
